How can the ocean be colder than 0 degrees C, the temperature at which water freezes? As it turns out, the concentration of the particles (in this case, the ions from the salt) in ocean water lowers the temperature at which the saltwater will freeze. Students will learn how ocean water freezes at a lower temperature than freshwater by
This article describes the work of a team of scientists using the latest in satellite tag technology to track the movements of the Weddell seal over the Antarctic winter. The project hopes to learn more about the animals as well as the ocean environment in which they swim.
Before leaving for the South Pole in late 2009, I received many suggestions for things to try down under. Liz Ratliff’s math classes suggested we try making ice cream! So, before I left, I had my students follow her recipe to make ice cream in our classroom in balmy California. After arriving at the pole, I was able
Given sets of graphable data students will show that various viewpoints can be supported depending on how data is presented and interpreted. These may or may not be accurate or relevant representations of data results over time. This lesson contains basic graphing components, interpretation of information and communication to others of findings depicted in graphs. Teachers may choose
